摘　　要：污水经生态滤池处理后,在微生物和蚯蚓的作用下,出水中COD、BOD5、总氮与总磷的浓度降低,磷的形态和组成发生了变化.进出水中的磷主要以溶解态为主,且PO43--P为主要存在形态,出水中溶解态磷占出水TP的比例增加.对进出水中磷质量平衡进行了估计.When wastewater was treated by eco-filter system, the level of pollutants such as COD, BOD5, total nitrogen and total phosphorus decreased and the ratios of phosphorus forms were different between the influent and the effluent. Both the influent and the effluent, dissolved phosphorus, especially PO4^3- P, was the main phosphorus form. After MEEF, the ratios of dissolved phosphorus to total phosphorus increased at 1m^3·m^-2·d^-1 and 2m^3·m^-2·d^-1, respectively. The mass balance of phosphorus was estimated.
